I have a couple of FRND codes as well, and could probably generate some if needed, I've only done the rounds with one email address.
I think I might have at least one FRIEND code, if they are still valid. I only got one book on the first time round with FRIEND as I did it before people posted about using multiple codes on one checkout and multiple browsers (multiple tabs in one browser never worked for me...) at the same time.
I don't want books in multiple accounts, so that was out for me. Might "travel" (or even simply travel
) one day, but only one account per country for me.
But luckily the FRND codes came along and I got 28 books in one go using 9 codes!!!! (Cost of 28 books: 36$ including a book originally priced @ 32$! )
That was enough playing the system for now, I totally cleaned out my wishlist (aside from books ineligible) as well as a number of spur of the moment purchases!
So PM if you want a code, I won't post them here, since that would pretty much rule out all the tricks to use more than one...
